Combine the tests test_return_binary_image_successfully and test_set_background_and_return_binary_image_successfully to optimize test execution and avoid redundancy. You can check both conditions in a single test since they are closely related. [important]

Consider refactoring the repeated setup code for initializing detector, background_image, and foreground_image into a separate setup method. This will make the tests cleaner and reduce redundancy. [important]

Consider optimizing the image loading in tests by loading the images once and reusing them, instead of loading them in each test. This will reduce the I/O operations and make the tests run faster. [important]

Consider adding assertions to check the actual content of the binary image, not just its existence. This would ensure that the binary image is correctly processed and meets expected conditions. [important]

It might be beneficial to add a cleanup step in your tests to release resources or reset the detector state after each test. This can prevent state leakage between tests and ensure that each test runs in a clean state. [medium]
